Download and install the appropriate driver here:

Assuming you are on a Windows system, go to Control panel/Sounds and devices/ and check that the Mbox2 appears as the default in the Audio and also Voice tabs/panes while unit is connected. If it is not, select it in each... if it is not in the list offered, then the drivers have not been installed for the Mbox.

Fuse would have NOTHING to do with the problem. Make sure to use balanced audio lines... XLR or TRS to mics or other devices.

The mbox mini is usb powered, wont work without power so your mac or pc must be powered on and connected. The blue led will be on when powered. Assuming you have the the appropriate cables, you want to make sure the condenser is plugged into the Mic/Line input. (Input 1 on the back of the mbox mini). All condenser mics require phantom power, so engage the +48V switch. Also make sure the DI (direct input) switch is not engaged. The input gain control is located on the front of the mbox... There needs to be speakers connected to the 1/4 output jacks on the back of the mbox or headphones on the front for sound output. Use the large knob for monitor volume control.
In protools: Create a Stereo Master fader track
Create a mono audio track
Set the input of the mono audio track to Mic/Line 1 Arm the track for record (click & make sure the R is red)
You should getting levels and sound output from your condenser.

Thiese links should help sort you out...

Have you tried it plugged into another computer, just to see if it gets power? If it quit working and it hasn't been too long, you may be able to get it replaced for free where you bought it or from digidesign (digidesign.com)

You were supposed to install the software first (which holds the drivers for the hardware) before you plugged in the MBox. I had the same problem, but I had to use drastic measures and reinstall my OS.

it doesnt sound like its the mbox more maybe the protools install. But as far as the cable goes can you tell me if you can ping the mbox throught the 1394 connection. If you cant ping it then damage may have been caused to the unit and it may need to be serviced. I fix my own M-box's but in my store it only costs around $50usd to fix almost all problems with a mbox2

un plug it uninstall the mbox and all the asio drivers. update protools. then reinstall the mbox and all the asio drivers you should be fine.
